I like the comment that religion is a-rational. It isn't rational because it doesn't proceed from scientific investigation, but it isn't irrational because it doesn't contradict my reasoning process.

I've said before, people who think there is a conflict between religion and science don't understand either one. If your science is based on a belief system, then it isn't scientific, and if your religion is based on provable/disprovable theories then it isn't faith.
